Actuators, position sensors, backup bearings, controllers, and the user interface are engineered as one integrated design.
Permanent magnet bias, homopolar: compact, low losses
Electromagnetic bias, heteropolar: fewer amplifiers, lower cost
Advanced control for rotor speeds up to 90,000 rpm
Automated commissioning through the graphical user interface
Active magnetic bearings hold the rotor in a magnetic field with no contact, so there is no wear and no lubrication. Oil-lubricated machines need pumps, separators, heaters, and periodic oil changes; Sapphire machines have none of them.
Non-contact support allows shaft speeds that ball and foil bearings cannot reach, enabling compact direct-drive machines.
Sapphire bearings support machines from tens to thousands of tons of refrigeration capacity, well beyond the limits of foil bearings.
AI-enabled diagnostics report rotor loading and vibration in real time, insight a conventional bearing cannot provide.
High-speed ball backup bearings carry the rotor through power loss and rapid restart, verified by drop test on every design.
Electromagnets hold the rotor in position with no mechanical contact. Sensors measure shaft position thousands of times per second and adjust the magnetic field in real time.
Backup touchdown bearings safely support the shaft during a controlled coast-down.
No. There is no oil system, no contact, and no wear in normal operation.
Eliminating contact removes the main wear mechanism in rotating machinery, reducing scheduled maintenance and extending design life.
